Too much sex

So i have a husband that has a really high sex drive like nympho status...so we get into these little arguments when i dont want to do it, now idk how everyone else is but we LITERALLY have sex 6 if not 7 days out the week...now my problem is i get sore n for some reason he doesn't understand that shit or to selfish to care. If im like can i jus blow u n not sex i swear its an issue EVERYTIME.but im so over having the same conversation about me needn at least a 2day break...how can i tell him without hurting his damn ego that. Being married does not guarantee everyday pussy... Please ladies, gentlemen HELP MEEEEEE
